Ediacara approx. 550 million years ago Complex life starts to evolve. In the background are some frond-shaped Charnia. Nearby on the left are three Swartpuntia. The three white jellyfish-like organisms on the seafloor are Dickinsonia. On the seafloor are some sea anemone-like nemiana which may have had tentacles for catching food particles. In the foreground is a Kimberella, feeding on the bacterial mats by scratching with its proboscis. Another can be seen further back on the left.
